448 | * String literals must be recognized based on context - there is no | |
449 | * quoting or escaping support. There's also nothing to explicitly indicate | |
450 | * when a label section completes. We deal with that by ending a label | |
451 | * section whenever we see a line that doesn't include. | |
452 | * | |
453 | * As with the syslinux family, this same file format could be reused in the | |
454 | * future for non pxe purposes. The only action it takes during parsing that | |
455 | * would throw this off is handling of include files. It assumes we're using | |
456 | * pxe, and does a tftp download of a file listed as an include file in the | |
457 | * middle of the parsing operation. That could be handled by refactoring it to | |
458 | * take a 'include file getter' function. | |
